I'm tired seeing all these allusions to felatio (and actual felatio) in anime and manga. Is Japan really not that interested in pleasing women?

Hell, it's the same in JAVs and h-anime. Felatio scenes outnumber cunnilingus ones by an overwhelming amount based on what I've seen (and I've seen a lot). And even when there ARE cunnilingus scenes, barely any time is spent on them. You'd see the girl sucking the guy for 15-20 minutes, but the girl would only get eaten out for, what 1-2 minutes before getting penetrated. There's also the fact that women performing anilingus on men becoming more and more prominent, while the opposite is becoming scarce.

This is why I prefer lesbian erotica: because women treat women right. :D

By the way, when was the last time anyone's seen cunnilingus (or cunnilingus innuendo) in non mainstream h-anime? It was in Seikon no Quazer, right? Are there any more scenes like that?

Close enough to it. There are multiple sex scenes in the series, but because they never show any poles or holes, it's not actually considered to be hentai and so it manages to make it onto late night television.
